Earlier today a Twitter follower asked the tech man if the couple's dog Chip is liking the new addition to the family and Alexis said, "He's the best big brother. Very protective of her—sleeps in room w her, always around her & will puff his chest when new ppl approach."

Big daddy Alexis hasn't been able to stop gushing about his strong woman and his baby girl from the get-go. Almost a month after his first daughter was born, the proud papa posted a sweet tribute video to both mother and daughter.

But that's not all...

In July, Alexis lauded his fiancée to CNBC's SquawkBox, saying, "She's very good at a lot of things and well on her way to being an awesome mom too."

"At Reddit, it's really important for us to support men and women when they are welcoming a new member to the family and so we have a pretty generous parental leave policy," he added.

"I'll be taking off for six weeks myself and trying to do the best job possible as a new dad, a first-time dad."

"Women Are Tough"

Serena and Alexis Ohanian didn't find out the sex of their child, but the tennis legend told Vogue she always suspected it'd be a girl. "Two weeks after we found out [I was pregnant,] I played the Australian Open," she said. "I told Alexis it has to be a girl because there I was playing in 100-degree weather, and that baby never gave me any trouble. Ride or die. Women are tough that way."

"A New Power"

Before giving birth, Serena gave an in-depth interview to Vogue, where she discussed her inevitable return to the court. "I used to think I'd want to retire when I have kids, but no," she shared. "I'm definitely coming back."

"Walking out there and hearing the crowd, it may seem like nothing. But there's no better feeling in the world...If anything, this pregnancy has given me a new power. I think I've had a love-hate relationship with the idea of power...Not only me, but women in general sometimes feel that 'power' is a bad word."

"We Will Have A Lot to Talk About"

As a female in the sports industry, she's dealt with sexism first-hand. Serena told us, "It's something we have to deal with in our lives, and I think if it is a girl, mommy is probably one of the best people that has been dealing with it, so we will have a lot of talk about!"

"I Have Been Really Fortunate"

In conversation with E! News, Williams shared, "I have been really fortunate and I have had a really good pregnancy, and everything has just been really good. Sometimes I am walking in my house, and I'm like, 'I really like being pregnant.' I never thought I would say that. I am definitely [the type] that enjoys it."

"This Is What You Want"

"I knew it was coming. I was like, ‘Serena, you're 35, you're ready. This is what you want,'" the athlete recalled to Vanity Fair about learning of her pregnancy. "If you would have told me last year in October or November that I would have a baby, not be pregnant but have a baby, I would have thought you were the biggest liar in the world. This is kind of how I am right now. This is happening sooner than later, and it's going by so fast."

"All Those Lessons"

While making her keynote speech at the BlogHer Conference in June 2017, Williams touched on the greatest advice her mom gave her. "And so I feel like all those lessons [my mom] taught me about being so strong," she shared, "of proud of who I am, of being able to look anyone in the face and have confidence and speak with so much confidence is something that I really have been able to embrace and would love to teach my kid that."

"You Gave Me Strength"

After announcing her pregnancy in April 2017, she penned an emotional note to her unborn child on Instagram. "My Dearest Baby, You gave me the strength I didn't know I had," she wrote. "You taught me the true meaning of serenity and peace. I can't wait to meet you."

"I can't wait for you to join the player's box next year, but most importantly, I am so happy to share being number one in the world with you.... once again today. On @alexisohanian bday. From the world's oldest number one to the world's youngest number one. -Your Mommy."
